Connecting the TB Holder to the I/O Module
Procedure 5-3 Connecting the TB Holder to the I/O Module
1) Open the door of the I/O module.
2) On the TB holder, loosen the screw and turn the positioner so that the arrow points to
either A or B.
3) Tighten the screw.
4) With a screw driver, set the code key pin to a number from 1 to 6.
5) On the I/O module, using a screwdriver, set the pin to the same number (from 1 to 6.) This
ensures that the TB holder will not be accidentally connected to the wrong I/O module.
6) Slide the plastic lip on the bottom of the I/O module to either A (up) or B (down) (as in
Step 2).
7) Align the plastic lip with the flat edge of positioner on the TB holder and snap the TB
holder into the I/O module, (see Figure 5-6), fitting the code key pin into the code key.
8) If the extractor handles are extended, push them inwards, against the TB holder (see Figure
5-6.)
9) If a TB holder clip was attached to the I/O module, slide the cable between the two edges
of the clip, and press the clip closed to secure the TB holder to the module. See Figure 5-5.
10) Label the TBs wires with any desired user notes. The wires are numbered 1-20 or 1-40
depending on the model. The wire numbers correspond to the module pins.
11) To extract the TB holder from the I/O module front panel, extend the ejector/extractor
handles outward away from the module and pull on the handles.
